Re: [COOT] nan sigma when I try to make Dano map in expert mode

Yes, I think you'll need to run fft or cfft to make a dano map, and then 
read that in coot.


(Alternatively, some phasing programs offer LLG map coefficients, which 
are probably a better solution).

Could this be the problem?  If the column type is correct in your mtz
file, then possibly coot is attempting to use an amplitude column type
instead of an anomalous difference column type (would might be confusing
fft).

Of course, I wasn't even aware that coot would try to calculate these
maps internally, so I could be completely wrong.

[COOT] current Spacenavigator support

2009-07-02 Thread Murray, Michael (NIH/NIEHS) [F]
Hello all,

I am thinking about purchasing a Spacenavigator from 3Dconnexion.  I vaguely
remember Paul mentioning something about the device in a recent talk but I
can't quite remember the context.  I was wondering if it was compatible
and/or useful with Coot.  There was apparently some discussion on the board
about support in 2007 but I don't see any mention since.

Any information would be appreciated.  This would ideally work on a Mac
running OS X 10.5 but I could always dual boot into Linux if necessary.

best,

Mike
